The invention discloses a torque sensor fault detection method. When a torque sensor is normal when a vehicle goes straight, the vehicle points to a torque center point, but when the vehicle goes straight on an inclined road, the fault of the torque sensor is detected mistakenly due to the inclination of the road surface and the offset of the torque center point. If the direction of the rudder angle is opposite to the deviation direction of the detection value of the torque sensor, it can be judged that the torque sensor breaks down. If the torque sensor is in the same direction, the torque sensor travels on an inclined road, the torque sensor can be judged to be normal, and faults are not detected mistakenly.

    一种转矩传感器故障检测方法。车辆直行中转矩传感器正常时,指向转矩中心点,但在斜路上直行时,由于路面倾斜,转矩中心点偏移,误检测转矩传感器故障。如果舵角的方向与转矩传感器检测值的偏移方向相反,可判定转矩传感器出现故障。如果在同方向,则在斜路上行进,可判定转矩传感器正常,不误检测故障。
